[SoCal428i]

Hi all,

I purchased a '14 428i M Sport. Previous owner had already done a "exhaust delete". At first I thought it was pretty cool but given I do a fair amount of freeway driving, the "freeway drone" is driving me crazy.

Are there any reasonably priced aftermarket options to tone it down a bit?

I think the M perf produces the least amount of sound even with a delete compared To aftermarket. Your best bet would be going OEM or finding a M perf without the delete. I had a delete done on my M perf and the noise level was only slightly higher, and raspier.

I think you are mistaking a resonator delete with a muffler delete. Can't have a muffler delete and the mperformance exhaust as it's a muffler lol.


But he's right mperf used, or a stock muffler will be your cheapest bet. Unless you get into a custom set up.

A simple single inlet dual outlet muffler (readily available at any exhaust shop) and some piping and you will be quieter than a delete.

If interested, I have an OEM exhaust for the 428i....PM me if interested......I replaced mine with the m-sport bmw exhaust and still have the original that was swapped out for.....OEM is super quiet and sounds like what you prefer...
